 Primary and secondary school plastic runway compulsory new national standard: formaldehyde should not exceed 0.4 mg


The compulsory national standard Playground for Synthetic Material Surface Layer in Primary and Secondary Schools was drafted by the Ministry of Education with dozens of scientific research institutes and testing institutions. After more than two years of revision, it began to be implemented on November 1, 2018. Drawing lessons from the relevant standards at home and abroad, the new national standard aims to solve the outstanding problems of safety, environmental protection and sports protection in the construction of synthetic material surface sports venues, and comprehensively considers the main risk points of each link in the whole life cycle of primary and secondary school synthetic material surface sports venues, and puts forward the green development and technology. Technical indicators for progress, industry standards and student health protection requirements.

Compared with the relevant old national standards, the new national standards not only changed from national recommendation standards to national compulsory standards, but also added many contents, including thickness requirements, physical properties, inorganic filler content requirements, anti-skid rubber particle polymer content requirements, harmful substances limits of surface products, harmful substances of non-solid and solid raw materials.

The reporter of Beiqing Daily saw that the new national standard has stipulated 18 kinds of harmful substances which may be produced in the construction of campus plastic runway, and has made the limit of volatile organic substances in the built runway according to the standard of household decoration. For example, Harmful substance limitation and odor requirement in cast-in-place and prefabricated surface products, total volatile organic compounds should not be higher than 5 mg/cubic meters, formaldehyde should not be higher than 0.4 mg/cubic meters, carbon disulfide should not be higher than 7 mg/cubic meters, benzene should not be higher than 0.1 mg/cubic meters and odor grade should not be higher than 0.4 mg/cubic meters. No more than 3. The new national standard also formulates in detail the sampling requirements, inspection rules and judgment rules of plastic runway in primary and secondary schools.
